Abstract
One new flavonostilbene glycoside, polygonflavanol C (1), two new dimeric stilbene glycosides, multiflorumiside M and multiflorumiside N (2−3), one new diphenyl ethanol glycoside, (R)-2,3,5,4′-tetrahydroxy-diphenylethanol 2-O-β-D-glucopyranoside (4), and one new deoxybenzoin glycoside, 2,4,3′,5′-tetrahydroxy-6-methyl-deoxybenzoin 2-O-β-D-glucopyranoside (5), together with six known ones (6−11), were isolated from the roots of Polygonum multiflorum. Their structures were elucidated by the comprehensive spectroscopic analyses. In addition, compounds 1 and 7 showed significantly in vitro anti-inflammatory activity.
